Selective determination of plutonium and transplutonic elements (Am, Cm) in feces ashes
Description
A technique has been developed for the selective determination of the main transplutonic elements of the fuel cycle in feces ashes. The natural elements (U, Ra, Th and their isotopes) usually present in the human diet, are eliminated. Plutonium separation is carried out in a classical way by ion exchange resin. After elimination of U and Th, Am-Cm are collected on a millipore filter for α spectrometry or global counting. Yields are 95% (σ = 4) for Pu and 81.7% (σ = 6,2) for Am-Cm

La technique permet de doser selectivement dans les cendres de matieres fecales, les principaux transplutoniens du cycle du combustible. Les radioelements naturels (U, Ra, Th et leurs isotopes) normalement presents dans l'alimentation humaine sont elimines. La separation du plutonium s'effectue de facon classique au moyen d'une resine echangeuse d'ions. Apres avoir elimine l'U et le Th genants, le melange Am-Cm est recueilli sur un filtre millipore permettant la spectrometrie α (ou le comptage global). Les rendements obtenus sont de 95% (σ = 4) pour le Pu et de 81,7% (σ = 6,2) pour Am-CmFiles
